WEAVING MACHINES.

SPECIFICATION forming part of Letters Patent No. 590,937, datedSeptember 28, 1897.

Application file d July 13, 1896.

T aZl whom it may concern.-

Be it known that I, GEORGE H. SHELLA- BERGER, of De Kalb, Illinois, haveinvented certain new and useful Improvements in Poll- Cuts forWire-lVeaving Machines, of which the following is a specification.

The object of this invention is to provide an attachment forwire-weaving machines for the purpose of pulling out or withdrawing thefabric as the Weaving progresses.

The invention is applicable to many kinds of wire-weaving machines, suchas those employed for making woven-wire fabric used for a variety ofpurposes, including fencing,

I5 and is also applicable to barbed-wire machines and to machines formaking various styles of picketfeuce having as elements thereoflongitudinal wires interwoven with wire or wooden pickets.

My improved pull-out comprises a series of disk clamps mounted in pairsupon a rotatable shaft and turning therewith, one or both of said diskclamps being capable of a slight rocking movement, so as to enable thesepa- 2 5 ration of the proximate faces of the pairs of clamping-diskson one side of their axis to permit the entrance of the strand-wires ofthe fabric between them, and a series of opening devices in the form ofwedges, which enter 0 between the disks upon one side to open them andto permit such entrance of the strandwires and closing them tightly uponthe strand-wires at the opposite side.

The construction is such that the strands 3 5 are clamped and securelyheld through about one-fourth of the circular path of the periphery ofthe disk.

The opening device may be of various forms and the construction andarrangement of the 4.0 disks may be slightly varied. I prefer to adjustably mount the opening devices and arrange a thrust-spring so as toyieldingly sup-, port the wedges, in order to accommodate variations inthe thickness of the wires and to avoid a rigid construction.

In the accompanying drawings I have shown my invention in the preferredform and modification of certain of its structural features.

In the drawings, Figure 1 is a plan view.

Serial No. 598,953- (No model.)

Figs. 2 and 3 are side elevations sectional through a shaft and aportion of the framework. Fig. 4 is a transverse sectional view througha portion of the clamp-disks. Figs.

5 and 6 are face views of. the inner sides of the disks. Fig. '7 shows amodification in the 5 5 manner of mounting the openers; Fig. 8, amodification in the construction of the disks themselves.

In Fig. 8 the disk clamp 13 hasa wide hub, and the disk clamp 12 isapertured to pass over said hub and is adapted to rock thereon.

In such case a retaining-collar '26 is employed.

9 represents the framework, Which may be a portion of thesupporting-frame of a wirefabric machine. 10representsashaftmountedthereon, and 11 a driving-shaft.

On the shaft 10 are mounted a series of disk clamps, (shown in detail inFigs. 4, 5, and 0 and marked, respectively, 12 and 13,) as shown in Fig.l, both of said clamps being keyed so as to be rotated with the shaft,the key-seats shown in Figs. 5 and 6, and the key (marked 14;) in Fig.3.

The bore of the hubs is slightly larger than the diameter of the shaft,so that the disk clamps have a slight rocking movement angular to theiraxis. The members of each pair of disk clamps are maintained slightlyseparated at their peripheries through about threefourths oftheircircumferences and are held tightly closed against each other through anarc of aboutninety degrees. This is accomplished by the employment ofthe opening devices, which may be of the construction shown in Fig. 2,consisting of a wedge 15, having its front edge curved to enter betweenthe disk clamps. These wedges have stems 16, which slide in the guides17 and are backed up by the spring 18, which tends to thrust thembetween the edges of the disks.

In the construction shown in Fig. 3 the rolling wedges 19 are employed,mounted in the same manner as in. the previously-(la scribedconstruction.

In order to prevent the wire from entering too far, the disk clamp 13has an offset shoulder 20 and the disk clamp 12 has the overhangingflange 21. The inner edges of the disk clamps are preferably beveled orrounded, as shown, to permit the easy entrance of the strand-wires.

In Fig. 3 the disk clamps are shown as provided with shallow notches orrecesses 22 to receive the transverse pickets or stay-wires 23 of thefabric,

Obviously the structural details herein shown may be varied-as, forexample, one member of each pair of disk clamps may be stationary andthe other member permitted a slight rocking movement.

The operation will be understood without further description.

The device is adequate to pull out a wire fabric as the weaving thereofprogresses, and it may be driven either continuously or intermittently.By slightly varying the form of the wedge or the mounting of the diskclamps the latter may be made to clamp the fabric during a greater orless portion of their rotation. The clamping and releasing of the fabricis automatic, and the device, while simple in its construction andoperation, is adequate to pull out the fabric evenly, so as to insure auniform feed, and consequently even lengths of the longitudinal strandsof the fabric, and consequently an equal tension throughout the fabricand the avoidance of warping and twisting thereof, thus enabling thefabric to be stretched easily and evenly.

By using wedge-shaped opening devices and beveling the inner edges ofthe peripheries of the disk clamps all wear is compensated for. Thepull-out will work with little friction, requiring small power for itsoperation.

Instead of mounting the wedges upon springs their stems may bescrew-threaded, as shown in Fig. 7, and provided with adjustingnuts2-.t, or they may be rigidly mounted upon the-beam 25 and the lattermade adjustable.

I claim 1. In a pull-out for wire-weaving machines, a pair of rotatableclamping-disks adapted for the separation of their proximate faces onone side of their axis of rotation, and an opening device operatingbetween said faces at the peripheries of the disks, substantially as andfor the purpose described.

2. In a pull-out mechanism for wire-weav ing machines, the combinationwith a rotatable shaft, of a pair of clamping-disks mounted upon andsecured to rotatewith said shaft, and one or both disks capable of aslight rocking movement whereby the proximate faces of said clamp-disksmay be separated upon one side of their axis and clamped at the opposite point, substantially as described.

3. In a pull-out mechanism for Wire-weaving machines, the combinationwith a rotata ble shaft, of clamping-disks arranged in pairs mountedupon said shaft and adapted for separation at their peripheries, theinner edges whereof are beveled, and wedge-shaped opening devicesoperating between the peripheries of the disk clamps, substantially asdescribed.

4. In a pull-out mechanism for wire-weaving machines, the combinationwith a series of clamping-disks arranged in pairs and capable ofseparation at their peripheries, and a series of yieldingly-mountedopening devices having wedge-shaped edges adapted to enter between theedges of the disks, substantially as described.

5. In a pull-out mechanism for wire-weaving machines, the combinationwith a rotatable shaft, of a pair of clamping-disks mounted thereon andcapable of a slight rocking movement on the shaft; said disks having theinner edges of their peripheries beveled, one of said disks beingprovided with a shoulder or flange to form a seat for the strand to beclamped, and an opening device adapted to enter be tween the edges ofsaid disks whereby to separate them, substantially as described.

6. In a pull-out mechanism for wire-weaving machines, the combinationwith clampingdisks arranged in pairs, one of said disks having itsperiphery beveled and recessed to provide a shoulder, and the other ofsaid disks having its edge also beveled and provided with a flangeoverhanging the shoulder, each pair of disks being mounted so as to rockupon the support, and wedge-shaped opening devices,one for each pair ofdisks,and whereby their proximate faces may be separated, substantiallyas described.
